Abstract: PROBLEM TO BE SOLVED: To perform a vertical movement for a tilt adjustment of the column smoothly by a small force by a simple mechanism when a grain hopper is loaded to or unloaded from a carrying vehicle such as a truck by providing a stretching device in the direction to be orthogonal to the tilt part of the stand of a standing device having a caster on both side frames. SOLUTION: A frame body 2 supports a hopper bottom part 14, and a boss body 11 is provided on the frame body 2 on a side surface. A receiving fitting 9 is located in the vertical direction, and extends in the horizontal direction together with a lateral shaft 10 on the inside, and the leading end of the lateral shaft 10 is inserted in the boss body 11. The top of a column 7 is connected to the receiving fitting 9 by a connecting pin 15, and is formed rotatably to the outside. A stretching device 6 is bridged between the receiving fitting 9 and a tiltable column 7, and freely adjusts the tilting angle. When the stretching device 6 is contracted from the solid line location of the column 7, the column 7 erects at the location of the imaginary line, and the hopper rises, and is fixed to the receiving fitting 9 by a lower pin 16.

IPC: H03K5/01
Filed: 1985-02-20
Abstract: PURPOSE:To obtain a simple circuit with highly accurate hysteresis characteristics by poviding the 1st differential comparator producing an output with an input voltage being the 1st discriminating voltage or over and the 2nd differential comparator producing an output with an input voltage being the 2nd discriminating voltage or below lower than the 1st discriminating volt age. CONSTITUTION:The 1st reference potential V1 from a potential generating source 1 is inputted to a non-inverting input terminal 5 of a differential amplifier 4 and the 2nd reference potential V2 from a potential generating source 2 is inputted to an inverting input terminal 10 of a differential amplifier 8. In the hysteresis circuit as above, an output of an RS flip-flop circuit 12 is not inverted until an input potential VIN reaches the 1st reference potential V1 from the lowest potential, and when the input potential VIN exceeds the 1st reference potential V1, the output of the RS flip-flop circuit 12 is inverted. In this case, an output inverted level of the differential amplifier 4 has only an error of the input offset voltage to the 1st reference potential V1 to eliminate the variance in manufacture.

IPC: G11B7/004
Filed: 1982-03-02
Abstract: PURPOSE:To suppress the oscillation of a system of tracking and to enable the stable pull-in of tracking, by detecting the presence of micro spot light right above the guide tracks and the absence thereof in address information regions of sector separating information regions in the stage of pull-in of tracking and leading in the tracking at the instant of said detection. CONSTITUTION:Grooves 2a-2e of width W, pitch P and depth J are dug on the surface R side of an optical disc 1. The grooves 2a-2e constitute guide tracks and are formed concentrically or/and spirally. The guide tracks are separated from each other by the flat parts 3a-3e between the grooves. A photosensitive recording material is vapor deposited on the surface R side, thereby forming a recording layer 4. Micro spot light 5 is irradiated from, for example, the surface side of a transparent substrate 6, and focuses on the surface R, thus recording information. The places where the information is recorded are in the bottoms of the guide tracks 2a-2e. The recording bits recorded in the row of bits in varying densities recorded in the bottom of the track 2e have higher light reflectance thereof than the light reflectance in the unrecorded parts.

IPC: H04L7/08
Filed: 1988-02-16
Abstract: PURPOSE:To simplify the constitution of transmission/reception circuit and to make the size small in comparison with the case with using a special CODEC and a speed converter by using part of bits as synchronizing bits and sending the synchronizing bits while a synchronizing signal is inserted for each prescribed bit unit of a digitized voice band signal. CONSTITUTION:When a voice signal is inputted in a transmission circuit, a PCM coder 11 adopts the conventional PCM system to convert the signal into a digital signal of one sample 8-bit constitution and outputted as a digital signal string in 64kbps. Then the digitized voice signal outputted from the PCM coder 12 is introduced to a synchronizing signal insertion circuit 12, where the synchronizing signal F is inserted to the low-order LSB bit for each 8-bit and then sent to an auxiliary transmission line. Thus, it is not required to lower the bit rate of the digitized voice signal and to provide a bit for synchronizing signal insertion separately, and the constitution of the transmission circuit and the reception is simplified and miniaturized in comparison with a conventional system.
